CSC151 2009F, Class 10: Raster Graphics and RGB Colors

Admin:
* Quiz 2 returned (during lab).
  + We'll run the code to see what was expected.
* I have not yet graded assignment 2 or writeup 1
  I'm very sorry.
* Are there questions on writeup 2? 
  * Turn in ONE copy if you work with a partner
  * But please include your partner's name
  * (Include your partner's name as citation if you turn in separate
    copies.)
* assignment 3?
  * Hint from Harry and Kevin: 
    * Getting the image to show up can be hard.  Have help around
       (e.g. Tutoring tonight)
    * Start early!
  * What is the target for minimum number of scheme things?
    * I don't know
    * Do it nicely, not "Oooh, here's a clever way to get around the rules."
* We're hoping to distribute exam 1 on Wednesday.  
  + It will be due the following Wednesday.  
  + You will not have another weekly assignment due next Wednesday.  
  + You will still have a quiz on Friday.
  + You may get a lab writeup somewhere in the middle there.
* We're going to try something a little different today.  
  + I'll take questions about the readings , but won't lecture first.
* Tomorrow, we learn more about colors, but from a 
  very different perspective.  
  + Matt Kluber from Art will be lecturing.

Overview:
* Representing images, revisited.
* Pixels and colors: The basics.
* RGB colors.
* Those weird numbers.
